Dataview有四种展示格式：list、table、task、calendar。 本文只介绍前面两种。

语法总结

通过#标签

```dataview 
LIST FROM #标签
```

通过"文件夹"

```dataview 
LIST FROM "文件夹名"  
```

通过[ [ 文件链接 ] ]

选择链接到一个文件，或者从一个文件获取所有链接，即，获取反向链接或者出链

```dataview 
LIST FROM[[文件链接]]
```

或着

```dataview 
list from outgoing([[文件链接]])
```

表格 table

```dataview 
table FROM "文件夹名"  
```

任务 task

```dataview 
task FROM "文件夹名"  
```

示例说明

元数据

所有笔记中都有隐含元数据，下面属性值都可以在Dataview查询中直接引用。

属性	值	类型
file.name	文件 标题	字符串
file.path	完整文件 路径	字符串
file.link	文件的 链接	链接
file.size	文件的 大小（以字节为单位）	数字
file.ctime	文件 创建 日期	日期
file.mtime	文件上次 修改 日期	日期
file.day	笔记标题中包含的 日期	日期
file.tags	笔记中所有 标签 的 数组	数组

1. 创建示例笔记

除了上面笔记自带的元数据属性，我们还可以手动添加元数据，有两种方式：1）添加文档属性；2）行内添加。

示例：

1. 新建两页笔记Movie X test 和 Movie X test2，
2. 在笔记里复制粘贴下面内容，可以自己编辑修改：

--- 
genre: "action" 
reviewed: false 
---
# Movie X 
#movies 

**Thoughts**:: It was decent. 
**Rating**:: 6 

[mood:: okay] | [length:: 2 hours]

1. 增加文档属性

手动增加文档属性
属性添加后如下：
勾选源码模式查看：文档内会显示源码

2. 行内元数据

• 使用:: 添加

• 直接使用时，一行只能添加一个元数据。
  

• 在[ ]内使用，这种方法可以在同一行或者一段文字内添加多种属性数据。
  

Dataview 查询示例：

通过标签查询，以table格式

```dataview 
TABLE file.ctime, length, rating, reviewed,genre FROM #movies 
```

通过标签查询，以list格式

```dataview 
LIST FROM #movies
```
